Methods for detecting acetylcholinesterase in a brain of a patient, comprising administering to the patient a detectable amount of a radiolabeled compound of a class of benzisoxazoles or a pharmaceutically acceptable salt thereof, are disclosed herein. The methods are useful for diagnosing, estimating the severity of, or monitoring the progression of a dementia, such as Alzheimer's disease, in a patient. In a preferred embodiment, the benzisoxazole is:

which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important “housekeeping” enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
